Authority to regulate radioactive airborne effluents was given to the
U. S. Environmental Protection Agency (EPA) by the 1977 amendments to the
Clean Air Act. A computerized methodology for performing an interim assess-
ment of airborne radionuclide releases as the basis for regulatory action
has been supplied to EPA.1 Efforts are now underway to develop a more com-
prehensive methodology that can be the continuing basis for EPA assessments
and radiation standards development. The purpose of this paper is to
describe t'is integrated Computerized Radiological Risk Investigation
The CRRIS System
The CRRIS system is a modular system of computer codes. This design
allows for maximum flexibility in the use of CRRIS and for changing the
individual codes. The five computer codes currently comprising CRRIS and
their possible interactions are shown in Figure 1. The individual codes
are discussed in more detail below.
The PRIMUS code will generally be the first code run each time a new
set of released radionuclides (source term) is evaluated using CRRIS. This
is a program for the Preparation of Radionuclide Ingrowth Matricles from
User- 'pecified Sources. These matrices are output by PRI'US and may serve
as pert of the input for any or all of the other codes in CRRiS.
Here’s what’s next.
